On the lantern night in Chang'an, a dance startled the dragon. Gongsunli, a girl from the rabbit tribe, and Li Xin, the general guarding the border, met under the bright lights and made a one-year appointment with a red-leaf hosta. However, behind this encounter lies the bloody truth about the destruction of the Sunset Sea royal family fifteen years ago. When A Li discovered his special bloodline, and when Li Xin shouldered the blood feud of his family and went to the border alone, the two souls with their own secrets couldn't help themselves in the troubled times.
The yellow sand filled the sky outside the Great Wall, and he fought bloody battles to avert all dangers; the maple leaves in Chang'an turned red again, and she followed the trail and faced the mystery of her life experience. The undercurrent of the court conspiracy and the awakening of the ancient bloodline are intertwined into a huge web. When trust and betrayal are intertwined, when family, country and personal relationships are in dilemma, can they keep the oath of "the red leaves are the guarantee, and they will live up to it in this life" in the war-torn times?
This is a love story in troubled times that transcends identity and race. It is also a growth epic about self-identity and mission. In the war of the King's Continent, watch how Gongsun Li awakens from an agile dancer to a bloodline heir, and how Li Xin transforms from an aloof general to a guardian beacon, and together they compose a soul-stirring legendary love song.
